The water had a slightly weird aftertaste, but overall it was very tasty. 10/10 would go again.
Excelente lugar para caminar y hacer ejercicio al lado del mar y de la espectacular planta d tratamiento
Wastewater Treatment plant turned National Park. Great place to visit in the summer for a walk, sightseeing, roller skating, and fishing.
Wannabe tough guy is security there. Threatened one of my friends but backed down quickly. Definitely weak and unprofessional.
it's always 98.6 degrees for some reason down here. they have the best lemonade and chocolate bars. these people are professionals who never let a floater get away from them.
This place has great vibrations and atmosphere. Feels like home.
What an amazing walk! On windy days, dress very warm and plan on potentially protecting yourself and your camera from huge splashes of water! The waves come crashing over the walls during several parts of this walk! The views are stunning and you are facing the ocean the entire time! Waterproof footwear will have your feet thanking you!
I tell ya, You haven't been treated like wastewater until you've been to deer. I mean that in all the best ways. You go in feeling like gray water, and, then leave feeling fresh as a daisy. I only trust them with my waste water. I don't even know why someone would want to or even consider going anywhere else.
No complaints. They do their job well and keep the harbor clean.
